The Unsung Hero of Technic Building

While larger gears handle the heavy lifting, the humble 12-tooth bevel gear is the true workhorse of the LEGO® Technic system. Its small size and beveled teeth make it incredibly versatile, but it excels at one crucial job: transferring power smoothly and efficiently around a 90-degree corner. From the inner workings of a supercar's differential to the steering system of a small go-kart, this gear is an absolutely essential component for countless mechanical functions.

Creative Uses for Compact Power

This gear's compact design allows it to fit into tight spaces where larger gears simply won't work, making it a key part for any builder.

• Inside Differentials: Three of these gears are hidden inside every modern Technic differential, allowing the wheels to spin at different speeds for smooth cornering.
• Compact Right-Angle Drives: Use a pair of these gears to create a small, efficient gearbox that changes the direction of rotation by 90 degrees, perfect for steering systems or small actuators.
• Increasing Gear Ratios: Pair it with larger bevel gears to create compact gear reduction or acceleration systems in your custom machinery and vehicle builds.

No Technic project is complete without a handful of these. Stock up by exploring our full Technic gears collection.

A Little Piece of Trivia

The 12-tooth bevel gear (part 6589) was introduced in 1994, making its first appearance in the legendary 8880 Super Car set. It was created as a much stronger and more durable replacement for the older, notoriously weak 14-tooth bevel gear (part 6576) from 1980. Because three of these gears are used inside every Technic differential produced since 1994, the 12-tooth bevel gear is one of the most-produced and widely-used gears in LEGO history.
